sPncIFIcATIoN forming pere of Letters Patent No. 658,782. dated october 2, 1900.

Application filed August 4, 1899.

To all whom it may concern,.- n

Be it known that I, WARREN T. KELLOGG, of the village of Lansingburg, county of Rensselaer, and State of New York, have invented new and useful Improvements in the Construction and Arrangement of a Series of Connectedly-Working Angers, of which the following is a specification.

My invention relates to improvements upon the manner of mounting and arranging a series of angers for boring the sockets made to receive sash-balances, and more particularly to improvements upon that device of this class which is described and shown in Letters Patent No. 393,817, dated December 4,1888, these improvements. having for their object the combination, with a series of angers employed, of a stock wherein the angers may journal, a recess'formed in the stock for inclosing the connectinggears, together with a construction whereby the angers may be retained relatively to each other as to Vertical position. Y

Accompanying this specification to form. a part of it there is a plate of drawings containing three figures illustrating the application of my invention to a group of angers designed to bore a socket and recess for the face-plate of a sash-pulley with the same designation of parts by letter-reference used in all of them.

Of the illustrations, Figure 1 is a side elevation of the apparatus with one of the side plates removed and with the handle and gage shown in section. Fig. 2 is a side elevation of the apparatus with the angers in position for boring a socket and a recess for a faceplate for a sash pulley, with the wood in which the boring is being done shown in section. Fig. 3 is a section taken on the line 0c of Fig. 2.

The several parts of the apparatus thu illustrated are designated by letter-reference and the function of the parts is described as follows:

The letter S `designates the stock in which the angers forming the series are arranged to journal and to be operated. This stock is formed by two plates P P, which are connected together by means of screws d. The inner side of each of these plates P is made to form one-half of journal-bearing b2 for the Serial No. '726 ,0941 (No model.)

-Shanks of each of the angers to journal in, and the letters R designate a recess that is made crosswise in the stock for the gears operating the augershanks,onehalf of `this re-l cess being formed in the inner face of each of the plates P, as shown at Fig. 3.

` The letter A designates the centrally-located one of the angers with its shank a2 j onrnaling in one of the bearings b2 of the stock, and the letter G designates a gear- Wheel mounted upon the shank co2, Within the recess R, and provided with a collar a2 Where the shank a2 extends below the stock. The centrally-located auger A has connected to the upper end of its shank a shaft b3, to which power is applied to Work the series.

The letter A2 designates an anger, of which there is one located at each side of the central anger A. These angers A2 are each provided with a collar C on each of their shanks S2, below the bottom of the stock. The shanks of these angers A2 each have a bearing in one of those indicated at b2, wherein to journal, and they are each provided with a gear G2, mounted thereon within the recess R, and with each of these gears arranged to mesh into-the gear G on the centrally-located shank a2 to receive power therefrom.

The letters A3 designate two angers, of which there is one at each end of the series, and each of these last-named angers at their boring ends have shorter Shanks than those of the angers located between them. The Shanks S3 of each of these angers AS are arranged to journal in one of the bearings b2, and they are each provided with a collar C2 where eX- tending below the stock, and they each have mounted thereon to be within the recess R a gear-wheel G2, arranged in the said recess with each of said last-named gears being constructed to mesh into the next adjacent one of the two gear-wheels G2, so as to receive power therefrom. These angers are all of them arranged to bore intersecting holes, with the angers A2 having their cutting rotation moving in a direction that is opposite to that of the centrally-located anger, with the end angers A3 having the same direction of cutting rotation as the centrally-located auger A. As thus placed the upper surface of each of the gears G G2 and the gear G3 will be in guiding contact with the bottom snr- The letter L designates a gage arranged upon that end of the stock which is opposite to that at which the handle is attached, and this gage is connected to the stock for vertical adjustment thereon by means of a slot I,

formed in the gage L, and a set-screw T.

As thus constructed and arranged to be operated, when the augers are together actuated those of the series having the longest Shanks will com mence boring before those at the outer ends of the series, which have shorter Shanks than the others. As the augers are actuated to bore by the power applied to the central one A the stock and the angers descend until the bottom of the gage L comes in contact wit-h the surface of the wood being bored, when the boring ceases, although the angers may continue to turn. By this arrangement of having part of the augers bore before those at the ends of the series commence to bore a socket and recess for the insertion of a sash-pulley and its faceplate can be bored and a mortise bored for chiseling, so as to adapt it to receive ashouldered tenon.

By arranging the actuating-gears within the recess R they are protected from the in'-v trusion of chips and dirt, and by using in connection with the stock S the handle H a means is provided to hold and guide the device when power is applied to the shaft b3, said handle and the gage L enabling the operator to handle the device with ease. The adjust-ability of the handle allows the length of it on the side toward the operator to be regulated with vregard to the position and convenience of the latter. Without this he must necessarily be at a great disadvantage Whenever the conditions are changed, as from one piece of work to another, since his distance may have to change also, and an unadjustable handle which suited the former distance might be altogether unfit for the latL ter distance.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is-

In combination with a series of angers geared together and a shaft for operating them, a stock, in which they are journaled, provided with a passage-way at right angles to the said angers, a handle movable forward and back in said passage and a clamping device for adjusting the position of the said handle in the said stock, substantially as and for the purpose set forth.

Signed at the city of Troy, New York, this 31st day of July, 1899, and in the presence of the two witnesses whose names are hereto written.
